I've sent an email to Customer Service and received no reply, so I am hoping this will get me an answer: My coworker in our UK office placed an order for an item we have on our shop: http://www.shapeways.com/shops/wolfram The item was printed but it looked as if it had a water stain on it. The representative told her that it was because we only had one hole in the model and that reprinting it would not guarantee that it would not happen again. I had placed an order for the exact same item and it came in looking perfect. My question is how can we fix the model so that this will not happen? Is it a size issue or something else?
